Abstract
Tent structures are used in many places around the world in both cold and hot climates. They are often used in crisis situations, natural disasters and various types of rescue operations. In order to assess the thermal conditions inside the tent, it is necessary to know the thermal insulation of its external envelopes. The thermal insulation of the cover also determines the selection of equipment for heating or air conditioning the tent. The article presents tests of thermal properties of a tent fabric and the value of the heat transfer coefficient of thermal protection of an pneumatic tent. The thermal insulation of the tent covering consists of two fabric layers separated by an air gap. The research was carried out on the assumption that the tent would be used in cold and hot climate conditions. The thermal conductivity of the material and the conditions of heat transfer on its surfaces were determined. The obtained measurement data were then used to determine the thermal parameters of the tent’s thermal shield.
Highlights
Tents are used in many situations, often requiring quick construction of a temporary, closed room
Due to their simple structure, they serve as a temporary shelter for the poor, refugees or people affected by natural disasters [2]
If the tent is used in hot climates, they are needed to determine the Envelope Thermal Transfer Value (ETTV) and the Roof Thermal Transfer Value (RTTV)
Summary
Tents are used in many situations, often requiring quick construction of a temporary, closed room. Modification of the construction of building partitions through the use of various materials in thermal insulation layers, translates into lower costs of heating or cooling rooms, while ensuring appropriate thermal comfort conditions for people staying in them [12]. The inside of the tent consists of two zones, one from the entrance to the tent - the vestibule (unheated and not requiring cooling) and the other, depending on the external conditions, heated or cooled In these two zones, the external partitions are structurally different and have different thermal insulation properties. The parameters of the external partitions of the tent were tested for two cases of climatic conditions, the cold period, with the temperature outside the tent -30°C and the temperature difference between the heated zone and the external environment of 40 K, and for the hot, summer period, with the external temperature of 50°C and the difference temperature 30 K
